The <navref> element preceded the recognition that a <topicref> can refer sensibly 

to a DITA map or external Eclipse TOC XML file.

Given that recognition, I'd suggest that the <navref> should have href, format, type 

and scope attributes (with format defaulted to ditamap) and should deprecate mapref 

in favor of href. 

That way, once DITA supports local addition of attributes (which is a possible

windfall as part of the constraints proposal), the <navref> element could be refactored 

as a specialization of the <topicref> element with an added, deprecated mapref 

attribute -- which might simplify the base map vocabulary a bit in the long term.

Thanks,
